Description
Technical field
The utility model relates to a kind of theft-preventing protecting device, relates in particular to a kind of communication cable theft-preventing protecting device and special spanner.
Background technology
Along with the develop rapidly of China's economic construction, electric power and communication career have spread in all trades and professions of society.These communication cable many places are located in the air by pantograph in the field, socket steel strand wire between electric pole, and communication cable is fixed on steel strand wire by fixture.Fixture of the prior art often adopts the iron hook that communication cable is fixed on the steel strand wire; The employing clamping plate are also arranged, communication cable and steel strand wire are fixed on the clamping plate by hexagon-headed bolt.Yet, such fixture all adopts the hexagon-headed bolt of national standard, use general general utility tool such as monkey wrench or pipe wrench just easy to do nut to be disassembled, cause critical facility such as many communication cables stolen, cause heavy losses for collective and user.
Therefore, need transform existing communication cable fixture, especially the bolt on the fixture uses existing instrument to be difficult for being removed after the connection of employing bolt, thereby makes communication cable reach better protection.
The utility model content
In view of this, the utility model provides a kind of communication cable theft-preventing protecting device, uses existing instrument to be difficult for being disassembled after the connection of employing bolt, thereby makes communication cable reach better protection.
The communication cable theft-preventing protecting device that the utility model provides; comprise two clamping plate and the bolt that is connected two clamping plate; at least one clamping plate is provided with two parallel holding tanks; it is polygonal open slot that the bolt head of described bolt is provided with cross section; the open slot bottom is provided with outward extending backing pin, and the outer face of described backing pin is not less than the end face of bolt head.
Further, described two clamping plate are made by hard material;
Further, described bolt head is a hemisphere;
Further, described backing pin is arranged on the axis of open slot;
Further, described polygonal open slot is positive five polygonal-shaped openings grooves;
Further, the bolt hole that is provided with on described two clamping plate is the dormant bolt hole.
The utility model also provides a kind of special spanner of installation or removal communication cable theft-preventing protecting device; comprise handle portion and drive division; the polygonal header structure of described drive division for matching with the polygonal-shaped openings groove, drive division is provided with the pin shaft hole with the backing pin matched in clearance vertically.
The beneficial effects of the utility model are: adopt communication cable theft-preventing protecting device of the present utility model and special spanner; the bolt head of connecting bolt is set to polygonal open slot; the open slot bottom is provided with outward extending backing pin; the installation or removal bolt must adopt supporting special spanner; common instrument can not put in the open slot because of stopping of backing pin; thereby can't installation or removal, avoid the communication cable or the steel strand wire that are fixed in the communication cable theft-preventing protecting device stolen.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a cross section view of the present utility model;
Fig. 2 is the cross section view of bolt;
Fig. 3 is the cross section view of special spanner.
Embodiment
Fig. 1 is a cross section view of the present utility model; Fig. 2 is the cross section view of bolt; as shown in the figure: the communication cable theft-preventing protecting device comprises the clamping plate 1 made by hard material and clamping plate 2 and fixedlys connected the bolt 3 of clamping plate 1 and clamping plate 2; on clamping plate 1 and the clamping plate 2 two parallel holding tanks are set respectively; corresponding holding tank closes up back formation cable folder hole 4 and steel strand wire folder hole 5 on clamping plate 1 and the clamping plate 2; the bolt head of bolt 3 is hemisphere and the open slot that cross section is a regular pentagon is set; bottom at the open slot of described regular pentagon extends outward a backing pin 6, and the outside end face of described backing pin 6 is not less than the end face of bolt head.During installation; communication cable is installed in the cable folder hole 4; steel strand wire are installed in the steel strand wire folder hole 5; in the bolt hole of two clamping plate, screw bolt; compress communication cable line and steel strand wire; bolt common hexagon socket head spanner when installation or removal must adopt supporting special spanner because of the stopping in the open slot that can't stretch into regular pentagon of backing pin 6, avoids the communication cable or the steel strand wire that are fixed in the communication cable theft-preventing protecting device stolen effectively.In the present embodiment, the cross section of open slot is a regular pentagon, and the communication cable line mostly adopts the die nut installation or removal at present, and fail safe is higher relatively; Certainly also can adopt square open slot or other polygonal-shaped openings grooves.
The backing pin 6 of present embodiment is arranged on the axis of open slot of regular pentagon, is convenient to backing pin 6 processing, can reduce production costs.
Holding tank on clamping plate 1 and the clamping plate 2 is for outwards bending or being bent to form; between the two ends of clamping plate 1 and two holding tanks, dormant bolt hole 7 is set; be provided with and clamping plate 1 corresponding dormant bolt hole 7 on the clamping plate 2; bolt has more crypticity after being installed in the dormant bolt hole 7, has strengthened the anti-theft feature of whole protecting device.
Fig. 3 is the cross section view of special spanner, and as shown in the figure: special spanner comprises handle portion 8 and drive division 9, the polygonal header structure of described drive division 9 for matching with the polygonal-shaped openings groove, and drive division is provided with the pin shaft hole 10 with the backing pin matched in clearance vertically.When adopting this communication cable theft-preventing protecting device of these spanner installation or removal, pin shaft hole 10 is aimed at backing pins 6, and drive division 9 puts in the open slot, but just installation or removal bolt.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
